Extensões ao protocolo de comunicações EPCGloboal para tags Classe 1 utilizando autenticação com criptografia de baixo custo para segurança em identificação por radiofreqüência
Abstract
EPCGlobal communication protocol for RFID (Radio Frequency
Identification) does not ensure security and privacy for its system users. This fact makes
possible several kinds of security problems on RFID technology usage justifying that security
mechanisms should be added to communication protocol preserving the existing standards.
This work proposal is based on communication authentication usage making use of low-cost
cryptography with the TEA algorithm. The proposed mutual authentication mechanism was
specified and proved using BAN logic. All protocol specification has considered the
EPCGlobal standard for Class 1 tags as base adding security and privacy extensions to data
communication to get protection against several attacks. The results from this work include an
authentication protocol formal specification with cryptography allowing this way the protocol
standardization using as base the current Class 1 protocol.
